Errors of failure rate estimations Results of Weibull grading test can be affected by different factors: • Definition of failure and used hardware; • Method of approximation of test results with Weibull functions, or method of calculations; • Value of acceleration
About Photovoltaic Energy StorageIt has been suggested that failure of solid tantalum capacitors is due to thermal migration of impurities from the tantalum anode to flaws in the oxide layer. This implies, however, that leakage current gradually increases under normal operating conditions, an effect which has not been observed. An alternative hypothesis advanced here is that failure is due to …
